Jay Kreps commented on KAFKA-1476:
----------------------------------
This looks good to me.
One thing we should think about: does this make sense as a standalone command?
We have something of a history of making a new command for every possible thing
you could do. Often it is a little more usable if we group these together a bit
into logically related items. For example, I could imagine having a command
bin/kafka-consumers.sh --list-groups
or something like that that also performed other consumer-related commands.
This sort of the makes the tools a little more usable for users.
[~guozhang], [~toddpalino], [~nehanarkhede] what do you guys think? As we do
the consumer co-ordinator what admin operations are we going to want tooling
for? How does this relate to the consumer offset checker, should that be
combined? Let's think this through and then just name this thing appropriately
even if it only has 10% of the functionality we envision at the moment.
> Get a list of consumer groups

> Issue Type: Wish

> It would be useful to have a way to get a list of consumer groups currently
> active via some tool/script that ships with kafka. This would be helpful so
> that the system tools can be explored more easily.
> For example, when running the ConsumerOffsetChecker, it requires a group
> option
> bin/kafka-run-class.sh kafka.tools.ConsumerOffsetChecker --topic test --group
> ?
> But, when just getting started with kafka, using the console producer and
> consumer, it is not clear what value to use for the group option. If a list
> of consumer groups could be listed, then it would be clear what value to use.
